This is a pair of real wood frame that is handmade, one-of-a-kind piece. Unlike any other frame you've ever worn before, these collections carry the features of nature classically yet modernly. Technology of waterproof, splitting proof and mould proof all guarantee a lone time use over years. The metal base is surrounded by wood on top, making the frame double bridged. Large sized rectangular lenses allow both single vision and progressive correction needs. The total weight with lenses is 24g, even lighter than some plastic frames.
